The Wisconsin Innocence Project, led by Attorney Byron Lichstein,
has brought new DNA evidence to challenge a 1984 murder conviction
based on the controversial forensic technique of bite-mark analysis.

Lichstein has asked prosecutors to vacate the conviction of Robert
Lee Stinson, whose DNA has been found not to be that in saliva found on
the victim. A review of testimony from a dental scientist and law
professor that convicted Stinson is under way, and the entire field of
bite-mark comparison is being called into question. The only evidence
against Stinson in his 1985 was the bite-mark analysis.

Forensic experts reviewing the case have found that "there is little
or no correlation of Robert Lee Stinson’s dentition to the bite marks."
